The Powertrain Control Module (PCM) enables high cooling fan and detects an open or shorted circuit
Monitors the High Fan Control (HFC) primary circuit output from the Powertrain Control Module (PCM). The test fails if the HFC output commanded on (grounded), excessive current draw is detected on the HFC circuit or, with the HFC circuit commanded off, voltage is not detected on the HFC circuit (the PCM expects to detect VPWR voltage through the high speed FC relay coil to the HFC circuit).
